[Surgical treatment of macular hole and maculopathy associated with optic disk pits].

PURPOSE: To inform about the successful surgical treatment of the retinal detachment of the macula and macular hole, as a complication of the optic disc pit. PATIENT: The authors report about 32 years old patient with optic disc pit complicated with the retinal detachment and the macular hole. After pars plana vitrectomy with intraocular gas injection (20% C3F8) associated with the application of the autologous serum and follow up face down positioning, the retinal attachment of the macula and the closure of the macular hole were present. In the period 9 months after the operation the relapse of the retinal detachment was observed and the closure of the macular hole is still remained. Condition was treated by intraocular gas injection (1 ml C3F8) and argonlasercoagulation. During the period of more than a 13 months after the first operation and 5 months after the reoperation the retina is attached and the macular hole is closed. In campimetry, a detailed development of the central scotoma is documented. The final visual acuity with correction is 6/9, that is improvement in 3 lines in comparison to preoperative condition. CONCLUSION: The surgical treatment of macular hole by optic disc pit is currently the methods of choice. Using this methods successful anatomical as well as functional results could be obtained.

[Secondary implantation of posterior chamber intraocular lenses in reconstructive surgery of the anterior segment and infusion of fluid through the pars plana].

BACKGROUND: A deep anterior chamber can be perioperative maintained by irrigation solution or by viscoelastic material. By longlasting reconstructive procedures after penetrating injuries we use an infusion through a pars plana cannula. METHODS: Between January 1994 and February 1995 five patients (aged 17-28 years) underwent secondary IOL implantation after penetrating eye injury with traumatic cataract. The reconstructive procedure was performed 6-11 years after the injury and linear cataract extraction. In all eyes corneal scars, iris anterior and posterior synechias, vitreous prolaps, and fibrotic posterior capsule remnants were present. The preoperative visual acuity ranged from 0.05-1.0. A pars plana infusion cannula was positioned 3 mm posterior to the limbus. In one eye with glaucoma a trabeculectomy and in two eyes with a greater defect of the posterior capsule, a lamellar scleral flap for transscleral suturing of one IOL haptic were performed. Then the prolapsed vitreous between cornea and infusion cannula was removed using the vitreous cutter. Iris synechiae were blunt or sharp dissected, the cortical masses were aspirated, the fibrotic or calcificated lens remnants were ectomised and an IOL was implanted into the ciliary sulcus. Two haptics were transsclerally fixated. The follow-up period ranged from 4-18 months. RESULTS: The surgery duration ranged between 45-90 minutes. No perioperative complications were recorded. On the fourth postoperative day bleeding into the anterior chamber and vitreous in one patient with transsclerally fixated haptic was observed. The blood reabsorbed spontaneously within a week. No complications from the infusion cannula could be observed. The postoperative visual acuity is 0.1-1.0. CONCLUSIONS: The permanent pars plana infusion maintains a stabile anterior chamber depths and intraocular pressure. The deep anterior chamber allows long-lasting surgical manoevers with less risk of corneal endothelium damage.

[Endophthalmitis after lens surgery].

At the University Eye Clinic Bratislava we performed a retrospective study on the occurrence of endophthalmitis after lens operations. Over the years 1993-1995 we performed 2374 lens operations. Endophthalmitis occurred in 20 eyes (0.84%). Endophthalmitis occurred after uncomplicated as well as after surgical procedures with various perioperative complications. All patients were treated with antibiotics locally and parenterally. Nine patients were treated with steroids. In these patients we did not performed pars plana vitrectomy. Owing to endophthalmitis one eye was eviscerated. In one eye after previous vitrectomy for proliferative diabetic retinopathy developed later inoperable retinal detachment. In one eye was present an old retinal detachment before the cosmetic cataract extraction was performed. Without any complications were cured nine eyes. In eight eyes are remained iris synechiae and vitreous opacities. Two eyes lost light perception and one eye was without light perception already before cataract extraction. The final visual acuity was better than 2/60 in 70% of the eyes and better than 6/36 in 50% of the eyes.

[Perforation keratoplasty after pars plana vitrectomy and use of a temporary keratoprosthesis].

In 12 eyes of 12 patients with vitreoretinal abnormalities due to reduced transparency of the cornea perforation keratoplasty was performed after pars plana vitrectomy with the use of a temporary keratoprosthesis. The corneal transplant remained clear after a mean follow up period of 15.5 months in 5 patients (41.7%). The visual acuity improved in 7 patients (58.3%), however only three patients had a postoperative visual acuity better than or equal to 3/60 (6/18, 6/60, 3/60). The retina remained attached in 8 patients (66.7%).

[5-years' experience with transvitreal extraction of subretinal neovascular membranes].

Over the period between June 1992 and November 1997, 15 subretinal neovascular membranes were removed in the Department of Ophthalmology of the Comenius University in Bratislava. The age of patients ranged between 57 and 72 years. In 13 patients the membrane was caused by age-related macular degeneration, in one patient the cause was choroiditis of unclear etiology and in one patient the membrane was caused probably by age related changes combined with myopic changes in the macular region. In three eyes only subretinal membrane was present. In all other eyes were also subretinal haemorrhages, hemophthalmus, or retinal detachment present. The visual acuity ranged between light perception and 1/50. After membrane removal the retina was tamponated by silicone oil in 10 eyes and by expanding gases in four eyes. In one eye peroperatively occurred profuse bleeding from choroidal vessels and this procedure was interrupted. The follow-up period ranged form 5-52 months. During this period in nine patients were performed additional 12 surgical procedures. The visual acuity achieved is 0 in three eyes and in other eyes it ranged between hand movement and 5/50. Two eye atrophied. In one eye retinal detachment is present. Three eyes are still filled with silicone oil. In two of them the tamponade will be probably permanent. In nine eyes large areas of retinal pigment epithelium atrophy are present and in two eyes also subretinal fibrous membranes are present.

[Ultrasonic diagnosis of retinal detachment after internal tamponade with silicone oil].

The authors evaluate the results of ultrasound examination of 20 patients with retinal detachment (20 eyes) after pars plana vitrectomy with silicone oil tamponade. Ultrasound diagnostic method is necessary in cases with non-transparent optic media. Silicone oil in the space of vitreous cavity has a character of a swimming water-drop and his physical properties can change the echography results. Between the eye-wall and silicone oil is a virtual space, which could be well visualised by ultrasound. The patients are divided into 2 groups. In the 1st group there were 7 eyes with transparent optic media and retina was detached under the silicone oil. By ultrasound the retina detachment echo was localised between the echos of silicone oil and eye wall. In the 2nd group there were 13 eyes with non-transparent optic media. In 6 cases (41.6%) the retinal detachment echo was visualised. The retinal detachment was confirmed by vitreo-retinal surgery.

[Endophthalmitis after intraocular interventions].

BACKGROUND: Endophthalmitis is serious complication of intraocular surgery. At the University Eye Clinic Bratislava we performed a retrospective study on the occurrence of endophthalmitis after various intraocular procedures. MATERIAL AND METHODS: Over the years 1993-1995 we performed 2374 cataract extractions, 305 anti-glaucoma operations, 106 perforating keratoplasties and 926 pars plana vitrectomies. The charts of all patients were reviewed. The occurrence of endophthalmitis, type of surgery, perioperative complications, elapsed time between surgery and start of endophthalmitis, results of preoperative conjunctival smear cultures, final anatomical and functional results were evaluated. RESULTS: The frequency of endophthalmitis after cataract extraction was 0.84%, after antiglaucoma surgery 1.31% and 0.97% after pars plana vitrectomy. No endophthalmitis was found after penetrating keratoplasties. In most cases endophthalmitis began in the first three days after surgery. Endophthalmitis occurred after uncomplicated as well as after surgical procedures with various perioperative complications. The preoperative conjunctival smear cultures were sterile in 22 patients. Staphylococcus epidermidis was the most commonly cultured germ. All patients were treated with antibiotics parenterally and locally. Pars plana vitrectomy and intravitreal application of antibiotics was performed only exceptionally. Enucleation was required in two eyes and two other eyes become phthitical. 22 eyes recovered without serious complications. Five eyes were blind and in 11 eyes the final visual acuity was better than 6/36. CONCLUSIONS: Pre-, peri-, and postoperative measures must be improved to prevent postoperative endophthalmitis. In cases of endophthalmitis all therapeutical options have to be performed as soon as possible to save the patient's eye and sight.

[Evaluation of circulatory flow in vessels of the eye and orbit using color duplex ultrasonography].

Duplex ultrasonography is recent imaging, that allows simultaneous 2-dimensional imaging (B-scan) and Doppler evaluation of the blood flow. Information on blood flow is obtained by pulsed Doppler spectral analysis. The blood flow in vessels of our interest is colour coded. Using this technique we examined 140 eyes. 81 eyes in 48 healthy persons were examined. Based on this examinations, the blood velocity standards were calculated for age groups 19-40 and 41-76 y. There are demonstrated pathologic findings by intraocular tumor, tractional retinal detachment and various failures of blood flow in bulbar and orbital vessels.

[Use of the DK-Line OPSIA liquid perfluorocarbon].

Since May 1993 to February 1995 we have used "DK-LINE" OPSIA in 137 patients in whom were 161 procedures on 141 eyes performed. It was used in 116 retinal detachments, 29 of them were posttraumatic. 28x in the eyes with proliferative diabetic retinopathy, 8x by injuries of the posterior segment of the eye, 5x in dislocated lenses and 3x by the removal of subretinal membranes. At the end of retinal detachment surgery was retina attached in 94.2%. Peroperatively we recorded subretinal migration of PFCL in 16 cases. 13x was removed peroperatively and 3x later by the reoperations. In three aphakic eyes we recorded postoperatively small bubble of PFCL at the bottom of the anterior chamber. From two of them was fully removed by paracenthesis and from the third by the reoperation. Only 1x we used an internal tamponade in duration of 5 day. We recorded serious sero-fibrinous exudation in the anterior chamber and in the vitreous cavity over the level of PFCL.

[The CT image of the eyeball after pars plana vitrectomy using silicone oil for internal tamponade of the retina].

Cerclage and silicon oil induce significant changes in the CT image after the vitreous and the retina microsurgery. It is important to get to know the right estimation of the CT image. Cerclage has mainly effect on characteristic shape changes of eyeball. Hyperdensity shadow of the vitreous cavity in the CT image of the eye after silicon oil tamponade creates different physical quality among silicone oil, vitreous and aqueous humor.

[Intraocular lens implantation in traumatic cataracts caused by intraocular foreign bodies].

The authors reports about the group of 17 patients in whom an IOL was implanted in eyes with traumatic cataract caused by IOFB. In 8 patients varied the interval between IOFB removal and IOL implantation from 5 months to 5 years. In 7 patients was IOFB removal and IOL implantation performed in one procedure. In one patient was IOFB not removed and in one patient was IOFB removed 1 month after IOL implantation. In two patients was IOL implanted in AC, in all other patients in the bag or in the sulcus. Per- and postoperative complications are discussed. We lost one patient from the observation. The follow-up period of 16 patients varied between 6-56 months. The final visual acuity in 10 patients reached 0.8-1.0. Visual acuity only of light perception is at patient, after repeated vitrectomies for retinal detachment.

[Effective extraction of intraocular foreign bodies].

In 39 patients was removed an intraocular foreign body in the years 1989-1991. 12 of them in the anterior segment of the eye, 14 in the vitreous body, 11 in the retina and 2 in the posterior part of the sclera. From the anterior segment were all bodies removed with forceps. From the vitreous body and the retina were foreign bodies removed mostly by forceps after previous vitrectomy. Functionally the worst results were achieved in foreign bodies where pre-, or peroperatively retinal detachment was present. Visual acuity under hand movement was present in 12 eyes.

[Surgical treatment of subretinal neovascular membranes. Initial experience].

Since june 1992 to march 1993 we removed the subretinal neovascular membranes in 4 patients. In three of them, aged 72-75 years, the membrane was diagnosed by age-related macular degeneration. In 57-y. old woman the membrane originated presumable in an ethiologically uncleared choroiditis. In the last two patients we used technique after Thomas and Kaplan with special instruments from DORC. In one patients the visual acuity improved and in three patients remained same, or a little worse than before. The chirurgical removal of the subretinal neovascular membrane is an alternative mode in the treatment of these membranes.

[Diabetic retinopathy in children and adolescents under 18 years of age].

We found ophthalmoscopically microaneurysms in 22 patients from 189 diabetics (11.6%). The youngest patients with microaneurysms were two 11-years-old girls with 3 and 5 years lasting disease. The chance of retinopathy was growing with the duration of the diabetes. By fluorescein angiography we discovered retinopathy in 52 patients out of 126 diabetics (41.3%). The retinopathy was more often found among girls. Just in one case we found the early stage of preproliferative retinopathy. The retinopathy was more often found in diabetics with higher levels of glyconated hemoglobin. The extent of foveolar avascular zone is decreasing with the longer course of the diabetes. We recorded lower occurrence of diabetic retinopathy in patients treated at the Ist Department of Pediatrics in Bratislava. In the group evaluated in the years 1986-89 the occurrence of the diabetic retinopathy diagnosed ophthalmoscopically was lower than in the group of 1981-84.
